Want to upgrade to electric seats

[Can007]

I am looking for advice and some direction, I would like to upgrade my manual seats to electric leather ones, and was hoping one of you guys had some experience with this topic, Everything is possible but is it difficult???

Hey there! You would probably get a better response posting this in the H3 section. This section is for electronics as in radios and gadgets, not like seat controlls. If you post up over there I'm sure someone will know something about this. Seems like it wouldn't be too hard.

Are planning to instal OEM electric seats or aftermarket?
If you will go with OEM it shouldn't be any problems. I'm not 100% sure, but all of the rigs already prewired for electric seats.

The seats are easy to remove and if it is prewired you should see or feel the wires in the carpet under the seats. Beyond that, all of the controls are in the seat so the implementation is plug and play, if the wiring is there and you buy a whole new seat assembly. I doubt that you could adapt a current seat to have the power controls.

Correct, you can only buy a power seat and install. Usually there is a couple plugs for ground and battery on the main plug.

Word of caution, if the H3 has SWS (seat weight sensor) or SPS (seat position sensor) detection in the seats, it can affect airbag deployment (I think they do because my 06 manual seats are connected to a body harness). Also, on new model seats to not cut or damage any yellow connectors. You might get a surprise.

A base H3 seat and a leather (heated/power) seat are wired differently. I put heated/power seats in my H3T and I had to re-pin the fuse box and run the wiring. I think the plugs are also different. Luckily, I also had an H3 Alpha to compare the wiring. It is far from a bolt in project. All of the pins and plugs are available from GM.

It has both switches. What you call a seat weight sensor is the sensor in the passenger seat that determines a full size person is sitting there, so that will turn on the passenger air bag. No one in the seat means the passenger side airbag will not deploy in case of a frontal collision.

the seat position switch signals the SDM the seat position. If the seat is at a certain distance from the air bag, and the SDM estimates a stage two air bag deployment is required, it will deploy at stage two. If the switch shows the seat is close to the bag (meaning the driver is inches away from the bag) it will only deploy blow the bag at stage one. (Stage one is a less force full blow.)

And as noted by MTUH3, if the wire ends in a yellow connector; make sure to pull the air bag fuse. Yellow connectors denote the supplemental inflatable restraint system and that includes air bags, sensor, side air curtains, SDM (aka the black box) and the pretensioner system built into the front shoulder harnesses.
